Has anyone had any expectance with a BMW GS 1150 Adventurer after changing the under seat fuel mapping plug and going from PULP to ULP. I was wondering does the kilometres per litre of fuel lessen? If so by how much? Can anyone tell me how many k's they are getting to their 30lt tank? at what kind of speed and what kind of road surfacers? I am hoping to under take a 'outback' trip, and have a 550km no fuel stage. Although 'Morgan and Wacker' has told me I would get 600km to a tank I'm not seeing it. Might have to do with the speeds I've been doing. The off road riding would be at a slower pace but would be harder going. Thanks if you can help. W.D.
